  2. Outline 1 What are Digital Object Repositories From Closed to Open Access From Heritage to Education Using Existing Software Building Software

  9. Why Open Access? • Lawrence (2001): clear correlation between open access and impact in CS • Eysenbach (2006): double citation impact for open access as compared to closed journal • and closer to home… • Suleman (2006): • open access repository part of normal operations of department – formal record of research • open access archive used extensively by external parties • indexed aggressively by search engines • resources accessed almost immediately after deposit and consistently thereafter

  13. (Open Source) Repository Packages ?

  14. Outline 2 Using Existing Software What Repository Software does RIGHT? Arguments against Repositories Future (Im)perfect

  15. What does repository software do RIGHT? • Infrastructure • Digital Objects are stored/archived • Users can access items from the Web • Services • Search full-text and metadata • Browse by author/title/etc. • Interoperability • OAI-PMH interoperability • Ability to ingest and export items • Security • User roles and authentication

  16. Arguments against OA Repositories Digital Repositories are a lot of hype – the technology is actually not yet mature enough to be practical or usable! It is so difficult for us as poor institutions in South Africa, with few staff and inadequate facilities and training.

  17. Training, Policies, Staff, Tools, … • Training • Have you been to a Sivulile workshop? • Policies • Listen to the other speakers! • Staff • What proportion of your library staff are IT vs. how many customers use IT rather than physical resources? • Tools • Are they any good? or are the tools pure EVIL?

  18. Repository Evils ? • No integration with Windows/Linux/BSD • Modern operating systems have packaging systems – many IR systems are still distributed in “source code”. Why not?

  19. Repository Evils ? • Low-level Components • No clean external API to communicate with services within most systems. • None of DSpace, EPrints, Greenstone …

  20. Repository Evils ? • Customisation requires programmer! Date: Mon, 23 Oct 2006 20:58:20 +0100 From: Christopher Gutteridge <cjg@ecs.soton.ac.uk> To: "EPrints.org Technical List" <eprints-tech@ecs.soton.ac.uk> Subject: Re: [EP-tech] Chicago citation style and e-prints To show the family name first last you can do @creators;order= fg@ or gf gf= given family fg= family, given To change the seperators to what you wand add the following to your local phrase file (not system-phrases) <epp:phrase id= "lib/metafield:join_name">, </epp:phrase> <epp:phrase id= "lib/metafield:join_name.last"> and </epp:phrase> But that can't be set on a per-citation type level.

  21. Repository Evils ? • Customisation requires programmer! Date: Wed, 18 Oct 2006 10:24:45 +1300 (NZDT)Subject: Re: [greenstone-users] Another question: multivalued fieldsFrom: sw64@cs.waikato.ac.nz Hello Ed, You can use AZCompactList classifier, for which the "allvalues" parameter is the default. Also, you can use [sibling:Subject] or [sibling:Author] format statement to display all multiple values of Subject or Author in VList, RegardsShaoqun > Thank you for your help a few weeks ago. I did get a sample collection> working, and have just heard that the organisation is keen to continue – I> now need tog et a couple of things working that I didn't finish before. > One of those is allowing for multiple values for Author and Subject. I have> created additional columns in the .cfg file and put some test data in.> Where is the "allvalues" parameter put and can it be done through the GLI> or do I have to edit the config file?

  22. Repository Evils ? • Poor Scalability • Most systems do not scale well beyond small collections. EPrints DSpace source: Technical Evaluation of selected Open Source Repository Systems, Catalyst IT

  23. Repository Evils ? • Identity not easily removable • DSpace is the name of the software, not the archive!

  24. Repository Evils ?

  25. Repository Evils ? • Buy-In / Lock-In • How easy is it to switch from DSpace to EPrints to Fedora to … ?

  26. Repository Evils • Are these issues significant roadblocks? • Are they being addressed at all?

  27. Current Development Directions

  28. Current Research Directions • Fedora • Generic interface to scalable repository • Pathways / OAI-ORE • (Submit) Interface to repository components • OCKHAM • Service registry for composition of systems from components • DILIGENT • Scalability of repositories in a grid • AJAX • Interactive Web-based interfaces

  29. Future Im(perfect) • Repository software gets a lot RIGHT, • Repository software still has issues, • Software use should not require a programmer • Software is a means to an end, not an end • Software should be appropriately engineered for reuse on a large scale like other OSS tools • Software should easily integrated into other systems • … but most of these issues have been noted and/or are being actively addressed

  30. Bottom Line We NEED Digital Object Repositories Why? To store and disseminate knowledge When? NOW ! How? Use popular software packages • DONT PANIC! • You’re not alone • The software has issues but is constantly improving The easiest possible way So… But that doesn’t do everything I want ! • DONT WAIT! • The need is greater than the (perceived) technical problems

  31. Open Access and Institutional Repositories NOW!

  32. the end.
